64bit OS? This is probably irrelevant as Wheezy is newer than Lucid, but...
In Debian Wheezy I have no end of trouble with proprietary NVIDIA driver
due to multiarch transition, in the end my workaround is to remember to
sudo rm mesa software rasterizer (super slow)
/usr/lib/x86_64-linux-gnu/libGL.so and symlink it to the proprietary one
installed in /usr/lib/libGL.so - painful
claude@cappuccino:~$ ls -l /usr/lib/x86_64-linux-gnu/libGL.so
lrwxrwxrwx 1 root root 11 Oct 1 16:35
/usr/lib/x86_64-linux-gnu/libGL.so -> ../libGL.so
I am wondering if the ati proprietary driver might be to blame, but I am not
sure how to check this...
Dunno - is there some dual graphics laptop card thing that needs optirun
or what have you to get good performance?
check the output of glxinfo, whether your config supports such a setting.
$ LIBGL_DEBUG=verbose glxinfo | head
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
server glx extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,
GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control,
GLX_EXT_swap_control, GLX_EXT_swap_control_tear,
GLX_EXT_texture_from_pixmap, GLX_ARB_create_context,

you definitely don't want to see swrast stuff in the debug output (if
there is any)
